When а hоt оbject cоols, heаt energy is trаnsferred to the surroundings. When that happens there is a change in entropy in both the object and the surroundings. Suppose a hot iron bar transfers 100 kJ of heat energy to the surroundings by cooling, what is the increase in the entropy of the surroundings? Assume room temperature (25°C) for the surroundings and use the equation ΔS = q / T. Give your answer in units of J/K (we will not use J/mol.K in this case because we are not dealing with 1 mole of anything). K = °C + 273
